Abstract

PURPOSE: To provide a material-carrying mechanism capable of being compacted into a small size and further capable of setting sites for installing various food- molding machines and sites for manual works at favorite positions with spare space. CONSTITUTION: Plural carrying boards 1 are connected to each other in a circular shape capable of being bent in the lateral direction, and disposed in a guide frame 11 in a state capable of being rotated in the longitudinal direction with driving sprockets 19. Thus, a carrying route A having a substantially elliptic shape on the plane surface and using a pair of faced sides in the latitudinal direction as parallel carrying routes is formed. One of a pair of the parallel carrying routes of the carrying route A is set on the side on which a food molding machine is installed, and the other is set on the side for works such as the supply of ingredients, etc.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material conveying mechanism for sushi rice and other food molding machines.

[0002]

2. Description of the Related Art As a conventional material conveying mechanism of this type,
A belt conveyor device in which an endless belt is wound around two rollers that are axially supported at regular intervals, and the upstream transport path is linearly configured, and a disk-shaped turntable in which the transport path is circularly configured. It has been known.

[0003]

However, the above-mentioned belt conveyor device is provided with various food forming machines along a linear conveying path, for example, a food supply and supply mechanism, a forming mechanism, a wasabi coating mechanism, and the like. However, there is a problem that the device becomes large (especially in the longitudinal direction of the belt conveyor device), while it has the use of being able to sufficiently secure the supply location of the ingredient.

On the other hand, the turntable has the advantage that it can be downsized as a whole, but on the other hand, it is difficult to secure a sufficient place for installing the above-mentioned various food molding machines and a place for manually supplying ingredients. In addition, there is a problem that the turntable has to be increased in size in order to sufficiently secure these locations.

The present invention has been made in view of the above problems of the prior art, and a plurality of transfer plates are pivotally attached to each other so as to be connected in a bendable annular shape.
The guide frame is rotatably installed so that a pair of opposite sides in the short-side direction are formed into a parallel elliptical conveyance path, so that various food molding mechanisms can be installed and ingredients can be supplied manually. It is an object of the present invention to provide a material conveying mechanism of a food molding machine, which can be secured at a position convenient for food molding work with a margin and can be downsized as a whole.

[0006]

In order to achieve the above object, the material conveying mechanism of the food molding machine of the present invention has a guide frame in which a plurality of conveying plates are connected in a bendable annular shape in the lateral width direction. By rotatably installing the two sides of the short-side direction in parallel with each other to form a substantially elliptical conveying path in a plane, one of the pair of parallel conveying paths of the conveying path on the food molding machine installation side. In addition, it is characterized in that the other side can be installed on the work side for supplying ingredients.

[0007]

Operation: A plurality of transport plates are provided on the back side of them.
A plurality of connecting members each having the same width as the lateral width of the carrying plate are pivotally supported by respective supporting shafts to be connected in a bendable annular shape.

On the frame, a substantially elliptical plane is formed,
Moreover, a guide frame having a substantially U-shaped cross section is fixed horizontally,
The outer side portion of each of the above-mentioned transport plates is slidably fitted into an endless groove having a substantially elliptical shape in plan view of the guide frame.

The drive sprocket axially supported by the frame is disposed inside one end of the guide frame in the longitudinal direction, and the drive sprocket is fitted with the shaft supporting portion of each conveying plate and the connecting member. ing. The inner side portion of each transport plate is slidably mounted on a guide plate that is disposed inside the other end of the guide frame in the lengthwise direction and is urged outward by a spring and that has a substantially semicircular shape in plan view. ing.

As described above, the pair of opposite sides in the short direction are parallel transport paths, and the pair of opposite sides in the long direction are semicircular transfer paths, which are substantially elliptical in plan view.

Then, by intermittently rotating the drive shaft, on which the drive sprocket is fixed, in a predetermined direction by driving the ratchet wheel, the transfer plates connected in an endless annular shape by the drive sprocket are It is intermittently rotated along the guide frame and the guide plate into a substantially elliptical shape in a plane.

Therefore, it is possible to secure one of the pair of parallel conveying paths in the short length direction as a place for installing the food forming mechanism and the other as a place for manually supplying the ingredients, and to reduce the size by the above. Each place can be set to a position convenient for work.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, a plurality of conveying plates are connected in an annular shape and rotatably arranged in the guide frame, so that the conveying path of the food material is substantially flat. By forming an elliptical shape, since the pair of parallel conveying paths in the short direction is configured to be long in the long direction, one of the pair of parallel conveying paths is installed at various food forming mechanisms.
The other can be positioned as a material supply site by hand, and these sites can be set with a margin, and by making it a substantially elliptical shape in the plane, it is possible to make the longitudinal direction extremely shorter than the conventional belt conveyor device, so it is compact. In addition to downsizing, the range of work movement by human being is narrowed by miniaturization, and the installation location of the various food forming mechanisms can be set at a position convenient for management and work.
